Specification 01. Letters Patent.

Application filed March 22, 1916. Serial No. 85,942.

To all u'homit may concern:

Be it known that I, MANVILLE F. RoBisoN, a citizen of the United States, residing at Bar View, in the county ofTillamook and State of Oregon, have invented new and useful Improvements in Boxes, of which the following is a specification. I

This invention relates to boxes and has particular reference to a cigar box.

It is the primary object of this invention to provide a box wherein the bottom is capable of vertical adjustment, with a view of varying the'capacity of the box from time to time as a part of its contents is removed, thereby giving the box the appearance of being full.

To this end the invention consists of a number of corrugated resilient members secured to opposedwalls of the box and cooperating with spring catches carried by the bottom thereof to hold the latter in adjusted position. p

The use of the invention in connection with a cigar box is sufficiently characteristic ofits utilityv and admirably illustrates the invention, constituting one of its most useful applications, but it is to be understood that the device is applicable to other forms of boxes, and that such general application is contemplated by the claims.

In the drawing forming part of this specification like numerals of reference indicate similar parts in the several views and silient members.

Referring more particularly to the drawing A indicates a box of usual construction including side walls 5, end walls 6, and a bottom 7 which iscapable of vertical adjustment between the walled frame of the box, a cover being indicated at 8.

Arranged within the box and secured to the end walls 6 are resilient corrugated 1 members 9, arranged directly opposite each other and adapted to cooperate with the spring catches 10 to hold the bottom in adusted position. The opposite ends of the bottom are recessed to receive the vertical portions of the catches 10, the latter being substantially of lL-shaped formation and having their horizontal portions 11 secured beneath the bottom in any suitable manner. The vertical portions project a slight distance above the surface of the bottom and have their free ends rounded as at 12 to prevent binding between the parts as the bottom is adjusted in either upward or downward direction, the rounded portions 12 of course being adapted to be received between the corrugations whereby the bottom is supported in its adjusted position.

The resilient members 9 arepreferably hooked over the upper edge of the end walls 6 and secured at this point in any suitable manner, while the corrugated portion of the members normally incline toward the lower edge of said end walls, being spaced therefrom as shown in Fig. 5. Manifestly the tendency of the resilient members 9 is to project inwardly toward each other, while the tendency of the vertical portions of the catches is to extend in the direction toward the resilient members. whereby an effective engagement is obtained with a view of properly supporting the bottom] This arrangement is especially advantageous when the box is completely filled at which time the bottom supports the maximum weight, but as this weight is decreased by the consumption of a part of the contents of the box, at which time the bottom is adjusted upwardly the resilient members are moved closer to the end walls 6 as shown in Fig. 3.

In practice, as a portion of the contents is removed from the box, the bottom is pressed upwardly a requisite distance to give the box the appearance of being full, the bottom being adjusted step by step consistently with the consumption of its con-' tents, until the contents have been entirely removed. The bottom may then be lowered to normal position to permit the box to be again used if desired. The lower ends of the resilient members 9 terminate to provide a horizontally disposed flange 14: upon which the bottom of the box may initially. rest, and'which flanges serve to prevent the bottom from being moved entirely from within the'wall of the frame of the box as the latter is adjusted to its normal position.

The invention is extremely simple in its nature and can be manufactured at acomparatively small cost.

"What is claimed is 1. The combination with a box having a vertically movable bottom, of a plurality of oppositely. disposed resilient corrugated strips having their corresponding upper extremities hooked over the upper edge of the adjacent wall of the box and secured thereto, said strips normally converging in a downward direction and spaced from said Walls, said strips terminating to provide inwardly extending horizontal flanges disposed beneath the bottom plane of the box, and resilient catches carried by the bottom and engaging said corrugated strips for holding said bottom in adjusted position.

2. The combination with a box having a vertically movable bottom, of a plurality of oppositely disposed resilient corrugated strips having their corresponding upper extremities hooked over the upper edge of the adjacent wall of the box and secured thereto, said strips normally converging in a downward direction and spaced from said walls, said strips terminating to provide inwardly extending horizontal flanges disposed b'eneath the bottom plane of the box, and substantially L-shaped resilient catches secured to said bottom and having their vertical branches extending above the bottom and around it to engage in the corrugations of said strips for holding the bottom in adjusted position.

In testimony whereof I afiix my signature in presence of two witnesses.

MANVILLE F. ROBISON.
